Yup, they all have the same layout. There will be minor variations between a Jazz or Orchestral kit within the workstation itself for sections outside of GM drums, but otherwise the workstations have the same mapping.

That's my own bit of organization. I don't know of a Korg drum map that exists but I'd be surprised if there isn't an official one somewhere. I made a sophisticated Cubase drum map based off that... but that's for some tutorial down the road._________________paypal.me/CharlesFerraro
